Specification of Letters Patent. 3 Patented June 22, 1920.

Application filed September 29, 1919. Serial No. 327,061.

This invention relates to that class of slicmg machines in which a knifeor cutter blade has a reciprocating movement in actual use, an exampleof which forms the subject matter of my prior application for LettersPatent, Serial No. 2' 76,i73, filed February 12th 1917. And the presentimprovement has for its objects 1% a To provide a structural formationand association of parts whereina short and rapid vibration in ahorizontal plane is imparted to theknife or cutter blade during thegradual downward movement of the same through the material. undergoing aslicing operation and thus attain a rapid V and very effective cuttingaction.

To provide a sin'iple and eifieient means for feeding the material to besliced with the attainment of uniform regularity in the thickness of theslices produced and in which the feeding mechanismis adapted to be moveddown and out of'the way, when it is desired to oleanthe machine parts,all as willhereinafter more fully appear.

In the accompanying drawings:

Figure 1, is 'a front elevation of a slicing machine embodying thepreferred form of the present invention.

Fig. 2, is a plan view of the same.

Fig. 3, is a detail side elevation with parts in section, illustratingthe step by step feed mechanism of the machine.

Fig. 4, is a detail longitudinal section illustrating the adjustablecarriage of the serrated feed wheel of the machine.

Fig. 5, is a longitudinal section on line 5. 5. Fig. 1. j

At itsother end the carriage 7 is pivotally connected to the upper end of aradius link 9 which is formed with an elongated slot 10 having operativeengagement with the driving mechanism of the machine, as follows: I 11designates the primary power shaft of the machine, journaledlongitudinally in bearings at the side of. the abutment plate or wall 2,and preferably receiving motion through a pair of bevel gears 12 from atransverse countershaft 13 capable of convenient manual rotation.

14: designates a secondary power shaft arranged in parallel relation tothe primary shaft 11 and receiving slower speed therefrom through a gearwheel and pinion connection 15 as shown in Figs. 1 and 2.

16 designates a crank disk secured to the secondary shaft 14, and havinga crank pin engaging the elongated slot 10 of the radius link 9, andadapted to impart a downward oblique movement to the cutter carriage 7in actual use, and as set forth in detail in my prior application SerialNo. 276,473.

17 designates the cutter blade or knife of the machine, of a straightblade form, and

having a guide flange 18 at its back for sliding engagement in acorrespondingly formed guide channel in the carriage 7 aforesaid. In thepresent improvement the cutter blade 17 has a rapid and short strokereciprocation in the carriage 7 With a view to attain rapid andeffective cutting action and to such end has operative connections asfollows:

19 designates a sliding head or standard moving in transverse guides 20on the base 1 in adjacent relation to the aforesaid guide standard 3 andprovided with a vertical guide channel for engagement with a pin or stud21 on the side of the cutter blade 17 to form an operative connection between the parts which permits of an inde pendent vertical movement ofthe pin or stud 21 in said guide channel in the practical operation ofthe machine.

22 designates a lever pivoted to the base 1, with one end operativelyconnected to the sliding head 19 aforesaid, and with the other endconnected by a connecting rod 23 with an operating cam mechanism asfollows:

24: designates a cam disk fixed on the primary shaft 11 and form with anannular cam groove of a sinuous form, cngaginga roller 26 011 the end ofthe aforesaid connecting rod 23 to impart a number of reciprocations tosaid connecting rod 23, and to the associated sliding head 19 and cutterblade 17, with each revolution of the cam disk.

2'7 designates an adjustable gage board secured to the base 1 andadapted to maintain the article being sliced in proper position againstthe side abutment plate or wall 2.

28 designates one or more serrated feed wheels extending up through anda short distance above the top surface of the base 1, through suitableslots therein, and adapted for feeding engagement with the under surfaceof the material being sliced.

29 designates a carriage or frame hinged at one end to the under side ofthe base 1 and provided with ournal bearings for the carrying shaft 30of the feed wheel 28 aforesaid.

31 designates a spring associated with the carriage 29 and adapted toyieldingly force the same upward and maintain the feed wheel 28 inproper operative position.

32 designates a cam or eccentric mounted on the underside of the base 1and having engagement with the free end of the carriage 25), and adaptcd to move said carriage downwardly when it is desired to depressthe feed wheel 28 below the top' surface of the base 1 previous to acleaning operation on the machine parts. -And to such end the carryingshaft of the eccentric 32 is provided with an operating knob or handle33 for convenient manual operation.

34 designates a ratchet wheel fixed on the carrying shaft 30 of the feedwheel 28, and 35 designates a rock arm associated with said shaft andcarrying a spring dog or pawl 36 adapted for operative engagement withthe ratchet wheel 34 aforesaid.

37 designates an inclined lug formation on the rock arm 35 and l catedin the path of a corresponding inclined lug formation 38 on the radiuslink 9 heretofore described and so that as said radius link 9 nears itsvertical position the lug 38 will contact with the h1g3? to swing therock arm in one .trackway, a cutter direction and cause the dog or pawl36 to engage the ratchet wheel 34 and impart a partial rotation to thesame and to the feed wheel 28. Such operation takes place as the radiuslink 9 nears its vertical position and with the cutter blade 17 in acorrespondingly elevated condition to permit a free passage of thematerial thereunder.
